You are welcome Tiffany.
If he hasn’t contacted you the whole week, he is trying to make a statement. However, it will only last so long before he is unable to help himself but to reach out.
Let him do that first.
It is better for him to discover your plan of moving out after having reached out to you first.
It puts you in a more powerful position.
If you were to reach out to him first and tell him that you are moving out, he may feel that you are doing it to appease him and that his no contact strategy worked.
He will feel empowered by this.
You don’t want his head to get any bigger than it already is.
So, let him message you first.
